Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, specifically a vibratory feeder for screw feeding. Background Technology

[0002] A vibratory feeder is an auxiliary feeding device for automatic assembly or automatic processing machinery. It can arrange various products in an orderly manner. The feed trough is an important component of the vibratory feeder. The function of the feed trough is to use the vibration of the vibratory feeder to make the screws move along the feed trough, so as to realize the transfer from the vibratory feeder to the next process.

[0003] The material trough of existing vibratory feeders is usually composed of a spirally rising guide channel and a discharge trough. During use, the screw moves gradually upward from the bottom of the guide channel under the action of vibration, and completes the orientation arrangement during the movement. Then it is discharged through the discharge port of the discharge trough.

[0004] The existing vibratory feeder has the following problems: the size of the discharge port of the discharge trough is fixed, which limits its applicability. When the screws being transported are small, if the discharge port is too large, it may cause the screws to be loosely or messy, affecting the next process. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a vibratory feeder for screw feeding. By adjusting the size of the discharge port according to the size of the screw through the adjustment mechanism, the situation that the screws are loosely arranged due to the discharge port being too large and affecting the normal operation of the production line is avoided. This improves the versatility of the equipment and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vibratory feeder for screw feeding, comprising a body, a discharge groove provided on the upper surface of the body via a bracket, a guide channel provided on the inner wall of the body, the upper end of the guide channel being connected to the inlet of the discharge groove, and an adjustment mechanism. The adjustment mechanism includes a sliding seat, connecting rods, an adjusting plate, a guide plate, a rubber pad, and a drive assembly. A support frame is provided at the discharge port of the discharge chute. An adjustable sliding seat is mounted on the upper surface of the support frame via the drive assembly. An adjusting plate is mounted on the right side of the sliding seat via two connecting rods. A guide plate is rotatably connected to the rear end of the adjusting plate within a slot. A rubber pad is mounted on the right side of the adjusting plate, and the rear end of the left side of the rubber pad is fixedly connected to the right side of the guide plate. By adjusting the size of the discharge port according to the screw size, the mechanism avoids the situation where the screws become loose due to an excessively large discharge port, thus affecting the normal operation of the production line and improving the equipment's versatility.

[0007] Furthermore, the drive assembly includes a lead screw, a limiting rod, and a rotating disk. The lead screw is rotatably connected to a slot on the upper surface of the support frame. The outer surface of the lead screw is threadedly connected to a threaded hole at the lower end of the sliding seat. A limiting rod is provided on the rear side of the support frame. The outer surface of the limiting rod is slidably connected to a sliding hole at the rear end of the sliding seat. A rotating disk is provided at the right end of the lead screw to facilitate the normal operation of the drive adjustment mechanism.

[0008] Furthermore, the adjustment mechanism also includes a limiting component, which includes a limiting groove and ribs. Limiting grooves are provided on both the upper and lower sides of the discharge port of the discharge chute, and ribs are provided on both the upper and lower sides of the rear end of the guide plate. The ribs are slidably connected to the interior of the adjacent limiting grooves to facilitate the sliding limiting of the guide plate.

[0009] Furthermore, it also includes a microcontroller, which is located outside the main body and its input terminal is electrically connected to an external power supply to facilitate the normal operation of the device.

[0010] Furthermore, the adjustment mechanism also includes a distance sensor. A distance sensor is provided on the right side of the upper surface of the discharge port of the discharge trough. The output end of the distance sensor is electrically connected to the input end of the microcontroller to facilitate the measurement of the size of the discharge port.

[0011] Furthermore, the feed channel is spirally ascending, which facilitates the spiral ascent of the screw.

[0012] Furthermore, the bottom wall of the main body is provided with a guide seat, which is a frustum shape that is narrow at the top and wide at the bottom. The bottom of the guide seat is aligned with the lower end of the material guide channel to facilitate the conveying of screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Rotating the rotating disc causes the adjusting plate to move, which in turn drives the guide plate to rotate, gradually tilting the guide plate and changing the distance between the adjusting plate and the right wall of the discharge trough. The distance between the right wall of the trough and the rubber pad is measured by a distance sensor, which is the size of the discharge port. The size of the discharge port is adjusted according to the size of the screw. The tilted guide plate and adjusting plate guide and limit the screw, avoiding the situation where the screws are loose due to the discharge port being too large, which would affect the normal operation of the production line and improve the versatility of the equipment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This embodiment provides a technical solution: a vibratory feeder for screw feeding, comprising a body 1, a discharge trough 2 provided on the upper surface of the body 1 via a bracket, and a guide channel 7 provided on the inner wall of the body 1, the upper end of the guide channel 7 connecting to the inlet of the discharge trough 2. (The body 1 adopts a common electric body structure in the prior art, consisting of a chassis (for different working scenarios and material characteristics), a controller (for controlling the vibration frequency, amplitude, and other parameters of the vibratory feeder), a feed pan, a leaf spring provided between the chassis and the feed pan, an armature provided at the bottom of the feed pan, and a pulse electromagnet at the upper end of the chassis. The controller controls the pulse electromagnet to be energized, causing the pulse electromagnet to operate, and the pulse electromagnet generates a large pulse...) The magnetic force attracts the armature to move closer, causing the tray and leaf spring to move to the left together. Then the controller stops energizing the pulse electromagnet, and the tray and leaf spring reset. During the repeated energizing and de-energizing operation of the pulse electromagnet, the tray will generate high-frequency vibration. At this time, the screw can be poured into the tray. The screw is subjected to the high-frequency vibration of the tray and will move spirally upward along the guide channel 7. During the upward movement, it is guided by the guide channel 7 and the discharge chute 2. The screw can automatically enter the assembly or processing position in a uniform state according to the assembly or processing requirements. The guide channel 7 is set on the inner wall of the tray of the body 1, and the discharge chute 2 is set on the upper end of the tray of the body 1 through the bracket.

[0018] It also includes a microcontroller 5, which is located outside the main body 1. The input terminal of the microcontroller 5 is electrically connected to an external power supply. The material guide channel 7 is spirally ascending. The bottom wall of the main body 1 is provided with a guide seat 6, which is a frustum shape that is narrow at the top and wide at the bottom. The bottom of the guide seat 6 is aligned with the lower end of the material guide channel 7.

[0019] It also includes an adjustment mechanism 3; the adjustment mechanism 3 includes a sliding seat 31, a connecting rod 32, an adjustment plate 33, a guide plate 34, a rubber pad 35, and a drive assembly 36. A support frame 4 is provided at the discharge port of the discharge trough 2. An adjustable sliding seat 31 is provided on the upper surface of the support frame 4 through the drive assembly 36. An adjustment plate 33 is provided on the right side of the sliding seat 31 through two connecting rods 32. A guide plate 34 is rotatably connected in the groove at the rear end of the adjustment plate 33. A rubber pad 35 is provided on the right side of the adjustment plate 33. The rear end of the left side of the rubber pad 35 is fixedly connected to the right side of the guide plate 34.

[0020] The drive assembly 36 includes a lead screw 361, a limiting rod 362, and a rotating disk 363. The lead screw 361 is rotatably connected to a slot on the upper surface of the support frame 4. The outer surface of the lead screw 361 is threadedly connected to the threaded hole at the lower end of the sliding seat 31. (Specifically, a bellows is fitted on the exposed part of the outer surface of the lead screw 361. The ends of the bellows are fixedly connected to the side of the slot and the side of the sliding seat 31, respectively. The bellows has sufficient length. When the sliding seat 31 moves, the bellows on one side contracts and the bellows on the other side extends, so that the bellows always wraps around and shields the lead screw 361 during operation, preventing dust from affecting the threaded transmission of the lead screw 361 and the sliding seat 31.) The limiting rod 362 is provided on the rear side of the support frame 4. The outer surface of the limiting rod 362 is slidably connected to the sliding hole at the rear end of the sliding seat 31. The rotating disk 363 is provided on the right end of the lead screw 361.

[0021] The adjustment mechanism 3 also includes a limiting component 37, which includes a limiting groove 371 and a rib 372. Limiting grooves 371 are provided on both the upper and lower sides of the discharge port of the discharge trough 2. Ribs 372 are provided on both the upper and lower sides of the rear end of the guide plate 34. The ribs 372 are slidably connected to the interior of the adjacent limiting grooves 371. The adjustment mechanism 3 also includes a distance sensor 38 (the distance sensor 38 is a laser sensor. When the distance sensor 38 is working, it emits a short laser pulse and then measures the time it takes for the laser pulse to be emitted, reflected back by the measured object, and received by the distance sensor 38. Combined with the speed of laser propagation in the air, the distance between the distance sensor 38 and the measured object is calculated to obtain the required parameters. The distance sensor 38 is aligned with the rear side of the rubber pad 35). The right side of the upper surface of the discharge port of the discharge trough 2 is provided with a distance sensor 38. The output terminal of the distance sensor 38 is electrically connected to the input terminal of the microcontroller 5.

[0022] The working principle of this utility model is as follows: The operator rotates the rotating disk 363, which drives the lead screw 361 to rotate. The rotation of the lead screw 361 causes the threaded sliding seat 31 to move to the right under the restriction of the limiting rod 362. The movement of the sliding seat 31 drives the adjusting plate 33 to move to the right through the connecting rod 32. Since the lengths of the adjusting plate 33 and the guide plate 34 are fixed, the guide plate 34 rotates around the connection point with the adjusting plate 33. The rear end of the guide plate 34 slides along the limiting groove 371 through the rib 372. Meanwhile, the distance between the right wall of the material trough 2 and the rubber pad 35, i.e., the size of the discharge port, is measured by the distance sensor 38. (The left side of the distance sensor 38 is aligned with the right wall of the material trough 2. When the distance sensor 38 is working, it emits a short laser pulse. Then, it measures the time it takes for the laser pulse to travel from emission to being reflected back by the right side of the rubber pad 35 and received by the distance sensor 38. Combined with the speed of laser propagation in the air, the distance between the distance sensor 38 and the right side of the rubber pad 35 is calculated, thus obtaining the required parameter, which is the size of the discharge port. The distance sensor 38 presents the detected distance data to the microcontroller 5. The operator can see the size of the discharge port through the display screen on the microcontroller 5.) According to the size of the screw, the size of the discharge port is adjusted by rotating the rotating disk 363 so that the distance between the right wall of the material trough 2 and the rubber pad 35 is reasonable to guide and limit the screw of this size. This avoids the situation where the screws are loose due to the discharge port being too large, which affects the normal operation of the production line and improves the versatility of the equipment. When the main body 1 is working, the controller of the main body 1 controls the pulse electromagnet of the main body 1 to repeatedly turn on and off, and the pulse electromagnet repeatedly runs and stops, so that the pulse electromagnet repeatedly attracts the armature. When attracting, the armature of the main body 1 moves together with the material tray of the main body 1 and the leaf spring. When not attracting, the material tray is reset under the action of the spring force. During the repeated turning on and off of the pulse electromagnet, the material tray will generate high-frequency vibration. At this time, the screw can be poured into the material tray. At this time, the screw is subjected to the high-frequency vibration of the material tray and enters the guide channel 7 from below under the action of the guide seat 6. It moves spirally upward along the guide channel 7. During the upward process, it is guided by the guide channel 7 and the discharge trough 2, and then discharged through the discharge port of the discharge trough 2.

[0023] It is worth noting that the microcontroller 5 disclosed in the above embodiments can be an STM32F1, the ranging sensor 38 can be an LTF laser sensor, and the microcontroller 5 controls the operation of the ranging sensor 38 using methods commonly used in the prior art.
